Toilet Seat Hinge Eccentric Washer Pair
This is a pair of 36 mm eccentric flange washers for toilet seat hinges. Each one has a tapered centring cone (Ø24 to Ø16 mm) that sits in the bowl's mounting hole, and an 8.6 mm bolt hole set 2 mm off-centre, which clears M8 and 5/16 in seat bolts. Turn each washer to shift that hinge up to ±2 mm and centre a seat on bowls with wide, uneven or chipped holes. The broad flange also covers porcelain chips. Both washers print on one sprue; snap them apart at the two breakaway tabs.
